Dynamic proximity boundary for detecting proximate objects

Abstract

Providing a visual treatment based on proximity to an obstruction includes collecting, by a device, a sensor data for an environment, and determining a velocity of the device. A boundary of a volume around the device is determined based on the velocity. If a physical object is detected within the boundary based on the sensor data, then a notification procedure is initiated. The boundary of the volume dynamically changes as the velocity of the device or user changes.

The invention claimed is: 
     
       1. A method comprising:
 collecting, by a device, a first set of sensor data for an environment; 
 determining a velocity of the device; 
 determining a volume boundary of a volume around the device based on the velocity; 
 detecting a physical object in the environment based on the first set of sensor data; and 
 in accordance with a determination that the physical object intersects the volume boundary, initiating a notification procedure. 
 
     
     
       2. The method of  claim 1 , wherein the device is configured to present virtual content on a display, and wherein the notification procedure comprises removing the virtual content from the display. 
     
     
       3. The method of  claim 1 , wherein determining the volume boundary comprises:
 determining a point of origin for the volume based on the device.

       6. The method of  claim 1 , wherein the notification procedure comprises performing at least one selected from a group consisting of an audio notification, a visual notification, and a haptic notification. 
     
     
       7. The method of  claim 6 , wherein initiating the notification procedure comprises:
 determining a direction of the velocity; and 
 selecting a notification type in accordance with the direction.

       12. The non-transitory computer readable medium of  claim 8 , wherein the notification procedure comprises performing at least one selected from a group consisting of an audio notification, a visual notification, and a haptic notification. 
     
     
       13. The non-transitory computer readable medium of  claim 8 , wherein the computer readable code to detect a physical object in the environment based on the first set of sensor data comprises computer readable code to:
 obtain depth information indicative of objects in the environment. 
 
     
     
       14. The non-transitory computer readable medium of  claim 8 , further comprising computer readable code to:
 detect a change in the velocity to a second velocity less than the velocity; and 
 modify the volume boundary in accordance with the second velocity to obtain a second volume. 
 
     
     
       15. The non-transitory computer readable medium of  claim 14 , further comprising computer readable code to:
 in accordance with a determination that the physical object is absent from the second volume, cease the notification procedure. 
 
     
     
       16. A system comprising:
 one or more processors; and 
 one or more computer readable media comprising computer readable code executable by the one or more processors to:
